COOKER.

lowing is a specification.

My invention relates to improvements in cookers, and the objects of myinvention are:

first, to design a cooker whereby all classes of canned goods will becontinuously agitated Within their containing receptacles so that by thetime the cans leave the apparatus, the contents thereof will be cooked;second, to drive the operating part of the apparatus in such a manner asto economize in power; third, to'provide an apparatus of this classwherein the canned goods have a clear spiral path from the inlet to theoutlet through which the same pass without danger of clogging orjamming, and fourth,

, to dispense with all conveyers or elevators,

since the cans are passed by gravity into and out of the apparatus, anda cooker within my invention will be hereinafter particularly described,and what I claim as new will be pointed out in the claims forming partof this specification.

Figure 1 is, in part, a horizontal longitudinal section-on the line -11,Fig. 2, and in part a plan elevation, certain parts of the revolvingdrum being broken away to illustrate construction; Fig. 1 is afragmentary longitudinal section onrthe line I- Fig. 1; Fig. 2 is avertical cross section on the line 2-2, Fig. 1; Fig.3 is a fragmentarycross section on the line 3-3, Fig. 1; and Fig. 4 is a fragmentarysection on the line 4.4, Fig. 1. I

In the drawings, like characters of reference refer to the same parts.

A is any suitable container, or casing, designed to carry steam and hotwater. B are any suitable pipe couplings, by means of which the passageof water and steam into and from the said casing is controlled. Suitablyheld in the ends C of said casing is an axle D, which passes through thelongitudinal axis of, said casing A. This axis is preferably held frommovement, and the preferred means to effect this purpose is to key thesame by means of keys E in the said ends 0. The outer drum isconstructed as follows: loosely mounted on the axle D is a gear wheel F.This gear wheel is provided Specification of Letters Patent.

atv its inner side with a flange Gr which pro vides a supporting meansfor the .longitudinal members H which are supported at their oppositeends by the flange I of the toothed-ring 2. These .said' longitudinalmembers are preferably in the form of T- irons, and by means of theflanges 3 thereof, screws 4 or other fastening means. secure the saidlongitudinal 'members in place. As will be seen clearly upon referencetoFig. 2, there are no spokes or other members interfering with thepassage of the canned goods through the opening-5 of the ring 2.

The said longitudinal members H are preferably braced midway their endsby a ring 6, to which the flanges of said member are suitably secured.Thewebs 7 of said members H are spacedapart as are also the flanges ofthe said members, and these said webs are disposed radially, thusforming pockets 8 to receive the cans for the purpose hereinafterparticularly set forth.

The said longitudinal members H are also. secured to a bracing ring 9,at'the feed end of the machine, and between the ring 9 and the flange Gthe flanges 3 of the members H are cut ofi to permit the ready passageof the cans in to the pockets 8, as will be seen upon referringparticularly to Fig. 3. J ournaled in the ring 9 and in the flange I area plurality of round bars or shafts 10, which are posi-. tioned betweenthe flanges 30f the members H and extend partly into the pockets 8. 11are idlers mounted on shafts 12, journaled in suitable brackets 13.These idlerstrack against the flange 14 secured to or forming a part ofthe toothed-ring 2,,and so support this toothed-ring and its associatedparts. Similar idlers 11 track with the rings 6 and 9, and so giveadditional. support to the 'outer drum. 4

The outer drum rotates, and the preferred means of rotatin the samecomprising a drive-shaft 15 which carries pinions 16, one

drum with a continuous spiral path or runway 22. The said drum-sectionsare supported from the axle l) by any suitable means: for instance, eachdrum-section may be providedwith spokes 23 carried by the hubs 24mounted on the axle D. The flanges 19 are provided with openings 25 soas to permit the ready passage into the inner drum of the heat-conveyingmedium.

, The function performed by the bars or shafts 10 is that of insuringthe rotation of the cans during the period they do not track The saidcans, ll find, track withthe flanges 19 for one-half the circumferenceof'the inner drum, and for the remaining half of the circumference, theynaturally extend more or less well into the pockets 8 and away from theflanges 19. When the cans are in the position just described, by meansof the bars or shafts 10 which are rotated, the said cans are alsorotated during this portion of their path through the apparatus, withthe result that thecontents thereof are Carried by the casing A, is acurved toothedrack 26, secured by any suitable means to said casing asby flange-provided lugs 27, bolted or otherwise secured to said casing.As will be observed upon referring to the dotted lines in Fig. 2, thistoothed-rack extends a short distance above the horizontal diameter ofsaid casing, and as the bars or shafts 10 are provided with teeth 28, asthe said teeth are brought into mesh with the teeth of said rack, thebars 10 are positively rotated to effect the purpose before set forth.

The outer drum is rotated in the direction indicated by arrow in Fig. 3,and as the pockets 8 pass by the dischargeend of the feed chute 29, acan passes into the said ppckets. The co-action between the webs 7 andthe said cans tracking onthe flanges 19 will rotate these cans and soagitate their contents. ln due course, the cans pass at a tangent fromthe inner drum on to the dis charge chute 30, down which they roll bygravity.

To prevent the cans dro ping between the flan es l9 and the innere gesof the webs 7, as t ey enter the pockets 8, an adjustable trap in theform of an adjusting plate is provided. This plate a, is substantiallyof the same width as the distance between the flanges 18, and is securedby any suitable means such as the rivet h, to one of the drumsections17, through the medium of the flange 19 thereof. 'An adjusting screw-o,is

thoroughly agitated. A

' and disposed with their hare-ecu that the plate a, must be movedcloser to the drum section 17 supporting the same.

From my experiments, T have found that this apparatus not only reducescost of operation and time in cooking, but since the cooked contents aredischarged at the top of the apparatus, we can use nearly all water forcooking purposes.

Changes in construction may be made in various ways in the disclosureillustrated without going oiitside the scope of the appended claims.
